There's a reward of up to $5,000 for information that leads to identification and arrest of the man. Authorities describe him as a black male in his late 30s or early 40s, about 6 feet tall with a thin to medium build.

He entered the bank that Monday morning wearing a floral patterned niqab, a long maroon dress, a pink cardigan and large glasses, according to authorities.

Inside, he corralled bank employees and customers into the back of the lobby at gunpoint. He demanded money from the tellers and threatened to shoot if they did not comply, according to authorities.
